容纳腔5371和连接筒513的中心轴线可与转动组件50的旋转中心线C重合，使得转动组件50在带动俯仰组件10和机头组件30于水平方向转动的过程中，容纳于容纳腔5371和连接筒513中的线束70受到该水平转动的影响较小，从而使得线束70不易受到磨损，具有较长的使用寿命。The central axis of the accommodation cavity 5371 and the connecting cylinder 513 can coincide with the rotation center line C of the rotation assembly 50, so that the rotation assembly 50 can be accommodated in the accommodation cavity 5371 and The wire harness 70 in the connecting barrel 513 is less affected by the horizontal rotation, so that the wire harness 70 is less prone to wear and has a longer service life.
电机33驱动其输出轴331转动，以带动与该输出轴331相连接的扇叶35转动。The motor 33 drives its output shaft 331 to rotate, so as to drive the fan blade 35 connected with the output shaft 331 to rotate.
可以理解的，扇头的扇叶35可绕输出轴331的中心轴线D旋转。It can be understood that the fan blade 35 of the fan head can rotate around the central axis D of the output shaft 331 .
进一步地，机头组件30处于一俯仰角度后，机头组件30于水平方向沿水平转动旋转中心C左右转动，扇叶35还绕中心轴线D旋转，使得扇头处会产生较大的负压，从而吸入较多的空气，使得扇叶35可吹出较大的风，且风速较大。因此，本实用新型的风扇还具有送风距离远、风速强的优点。Further, after the head assembly 30 is at a pitch angle, the head assembly 30 rotates left and right along the horizontal rotation center C in the horizontal direction, and the fan blade 35 also rotates around the central axis D, so that a large negative pressure will be generated at the fan head , so that more air is sucked in, so that the fan blade 35 can blow out a larger wind, and the wind speed is larger. Therefore, the fan of the utility model also has the advantages of long air supply distance and strong wind speed.
本实用新型一实施例中，扇叶35包括主扇叶351和千叶353，轮毂上固设有多个主扇叶351，相邻主扇叶351间设千叶353，所述千叶353与主扇叶351在轮毂轴向上呈鸭式布局布置。扇头旋转时，进风侧气流经千叶353加速形成干扰主扇叶351气流的分离涡，于主扇叶351吸力面上产生将主扇叶351根部前缘堆积的回流带走的吸力，使主扇叶351根部前缘气流变得顺畅、实际做功面积增加，因而本扇头内流品质佳、效率高。使得扇头的送风范围更大、送风距离更远、风速更快。In one embodiment of the present utility model, the fan blade 35 includes a main fan blade 351 and a flap 353, a plurality of main fan blades 351 are fixed on the hub, and a flap 353 is arranged between adjacent main fan blades 351, and the flap 353 It is arranged in a canard layout with the main fan blade 351 in the axial direction of the hub. When the fan head rotates, the air inlet side airflow accelerates through the flaps 353 to form a separation vortex that interferes with the airflow of the main fan blade 351, and generates a suction force on the suction surface of the main fan blade 351 that takes away the backflow accumulated at the front edge of the root of the main fan blade 351. The airflow at the leading edge of the root of the main fan blade 351 becomes smooth, and the actual work area is increased, so the internal flow quality of the fan head is good and the efficiency is high. The air supply range of the fan head is larger, the air supply distance is longer, and the wind speed is faster.
通常，相对于流经扇头的气流，所述千叶353在轮毂轴向上的位置位于主扇叶351的上游，使扇头内流品质更佳。Generally, relative to the airflow flowing through the fan head, the position of the flap 353 in the axial direction of the hub is located upstream of the main fan blade 351 , so that the internal flow quality of the fan head is better.
本实用新型实施例中所述主扇叶351和千叶353分别为前弯掠和后弯掠设计，所述千叶353采用后弯前缘和直后缘造型且该后缘具有一前掠角。其中，所述千叶353与主扇叶351呈上位鸭式布局布置在轮毂上。需要注意的是，此处还可使所述千叶353与主扇叶351呈下位鸭式布局布置在轮毂上，增强扇头设计的灵活性。应当理解，所述主扇叶351还可以是后掠或直叶片设计。In the embodiment of the utility model, the main fan blade 351 and the flap 353 are respectively designed to be swept forward and swept back. horn. Wherein, the flaps 353 and the main fan blades 351 are arranged on the hub in an upper canard layout. It should be noted that here, the flaps 353 and the main fan blades 351 can also be arranged on the hub in a lower duck-like layout, which enhances the flexibility of the fan head design. It should be understood that the main fan blade 351 may also be a swept or straight blade design.
该机头机构100还包括面罩37，该扇叶35容纳于面罩37中。The handpiece mechanism 100 also includes a mask 37 , and the fan blade 35 is accommodated in the mask 37 .
电机33的输出轴331穿过面罩37与扇叶35连接。The output shaft 331 of the motor 33 passes through the mask 37 and is connected with the fan blade 35 .
在组装该机头组件30的过程中，无需对风扇的外观零部件进行组装，使得在组装该机头组件30的过程中不需要对外观件进行防护，大大的提升了生产合格率。该外观件可为风扇的外壳、按钮等部件。In the process of assembling the head assembly 30, there is no need to assemble the appearance parts of the fan, so that the appearance parts do not need to be protected during the assembly process of the head assembly 30, which greatly improves the production qualification rate.
